17
Q

Define Biodiversity?

A

The variety of life forms within a given ecosystem, region, or the planet.

18
Q

Define Genetic diversity?

A

The variation in genes within a species, allowing populations to adapt to changing environments and helps maintain overall species resilience.

19
Q

Define Species diversity?

A

The number of different species in a particular area, both the abundance and the number of different species present.

20
Q

Define Ecosystem diversity?

A

The variety of ecosystems within a given place, including the different types of habitats and ecological processes that occur in a region.

21
Q

Define Functional diversity?

A

The range of roles that organisms play in an ecosystem, including their interactions within an ecosystem.

22
Q

Q: What is Random Sampling?

A

A technique where every individual in the population has an equal chance of being selected.

23
Q

Q: How does Systematic Sampling work?

A

Involves selecting individuals at regular intervals from a list or spatial arrangement, such as every 10th individual.

24
Q

Q: What is Stratified Random Sampling?

A

Involves dividing the population into subgroups based on specific characteristics and then randomly sampling from each group to ensure representation of all subgroups.

25
Q

Q: What is Cluster Sampling?

A

Divides the population into clusters, selects a random sample of these clusters, and then surveys all individuals within the chosen clusters.

26
Q

Q: What is Convenience Sampling?

A

Involves selecting samples from a group that is easiest to access, which can lead to bias and may not represent the entire population.

27
Q

Q: Describe Purposive Sampling.

A

Involves selecting samples based on the researcher’s judgment because they possess specific characteristics relevant to the study.

28
Q

Q: What is Snowball Sampling used for?

A

Studying hidden populations. Initial subjects are selected and then asked to refer others who fit the criteria.

29
Q

Q: What does Quota Sampling involve?

A

Involves selecting a sample that reflects certain characteristics in proportion to their occurrence in the population, such as ensuring a specific percentage of males or females.

30
Q

Q: How is Point Sampling conducted?

A

Involves selecting specific points within a study area and collecting data from those points. It is used to assess species distribution or habitat characteristics.

31
Q

Q: What is Line Transect Sampling?

A

Involves collecting data along a line placed across the study area, with observations or measurements made at regular intervals.

32
Q

Q: How does Quadrat Sampling work?

A

Marking off a specific area of habitat using a frame and collecting data from within this area to estimate population density and distribution.
